In the flow of a full backcountry day you interact with your pack more than any other piece of gear¬¦¡ if it doesn't work seamlessly, you end up wasting time and energy. Sized for long days deep into the backcountry, the burly SnowDrifter has a design that compliments the unique demands of moving through the winter mountains under your own power. It has a dedicated compartment for snow safety tools with individual sleeves and pockets for your probe, shovel, snow saw and more. The large main compartment opens two ways¬¦¡ via a fast U-shaped zippered lid or a zip-open back panel to provide instant access to all your gear without unloading the pack. A separate microfleece-lined pocket keeps your goggles handy and protected from sharp edges. The suspension system incorporates heat-venting, snow-sloughing Air Flow mesh on the shoulder straps, back panel and padded waist belt for all-day carrying comfort. Front and side compression straps with locking cam buckles provide numerous carry options for your skis and boards. The top-mounted haul handle is reinforced and sized for gloves. Made from burly 420-denier 100% nylon Cordura plain weave for puncture- and abrasion-resistance, with a tough 940-denier 100% nylon Cordura Ballistic base with polyurethane coating. Both fabrics have a DWR (durable water repellent) finish.
